    Hi,
    I downloaded the demo version of the MySQL library
    https://store.codesys.com/en/mysql-library-sl.html
    When I try to run it on a PLC with Windows (either Delta AX8 or Codesys Control Win v3) and connect to an external MySQL server I receive an error: SOCKET_ERROR
    When running the same project on Raspberry Pi it works without any issues.
    Do I need to install something else?
    Thanks!

    MySQL server is on linux or Windows?
    I think could be a SSL related problem.

      Not sure, I'm using freesqldatabase.com just for testing.
      When I try connecting to the DB from HeidiSQL from my PC it's working fine so, is it something with the socket library that causing an issue with the SSL?

    Record the connection attempt with Wireshark. Maybe you can see something useful.

      I tried, but I think I don't have enough experience with Wireshark to understand what's going on there.
      I think it's hitting the timeout because the server sends the same TCP packet again.
